Digger

Digger was a footnote in the long history of the well-known band
Grave Digger.
After that band's third album failed to sell, the record label
recommended a name and style change, and so Digger was born.
The result was Stronger Than Ever, a less metallic, more hard
rockish affair, presumably geared toward a more mainstream audience.
The plan didn't work, though, as the album got poor reviews
and sold terribly, and in fact the band broke up soon afterward.
It would be six years before vocalist Chris Boltendahl and guitarist
Uwe Lulis regrouped, recruited new members, and recorded a demo
that eventually led to the continuation of
Grave Digger.
